COPLIN PLANTATION — Authorities will be investigating the scene of a fire Monday night that possibly was caused by a propane explosion.

The fire began around 8 p.m. Monday at a seasonal house at 113 Porcupine Trail. The structure was destroyed, and the blaze sent the lone occupant — Timothy Henderson, 71, of Ellsworth — to the hospital, according to Sgt. Ken Grimes, of the state fire marshal’s office.

Grimes thinks the fire was started by a propane explosion because that is what Henderson told firefighters, he said. Fire marshal’s investigators won’t know details of the cause until they examine the scene later this week, Grimes said. The fire marshal’s office and state propane examiners will investigate.

Firefighters worked six hours to fully extinguish the blaze, according to Eustis Fire Lt. Scott Statcher. Coplin Plantation is east of Carrabassett Valley and south of Eustis.

When the Eustis Fire Department first arrived at the house, it already was fully engulfed in flames, Statcher said Tuesday morning.

Henderson sustained non-life threatening injured and taken to Franklin Memorial Hospital in Farmington, Grimes said, and was later transferred to Maine Medical Center in Portland.

The Eustis Fire Department was assisted by the Carrabassett Valley and Rangeley fire departments.
